Samba

“Samba has been around for a long time and comes from a group of hackers in Australia. Their home page is http://www.samba.org. Samba is ported to many
flavors of Unix but is most popular on Linux.

If you have a Linux box and you want to network it with one or more Windows workstations, you will definitely want to run Samba. It allows your Linux
box to completely emulate a Windows NT server and you can set up a personal Windows NT network at a fraction of the cost.”
